ARROWHEADS

Arrows came with different heads, which served various functions. Long thin (bodkin) heads could prize apart and penetrate ringmail.
Broad-head or Barbed had flared heads that could not be removed without causing masses more damage to the unlucky warrior.
Chisel and Leaf shaped arrowheads do masses of damage to the muscle as they cut their way in and cause much blood loss as a result.
